I talked to them and they recommended not eating here if you were sensitive to cross contamination. They do have gluten free bun and options but they were wonderfully honest, which I appreciate, that if you’re a celiac or super sensitive to avoid. Shared fryers, etc.
I had the Stars & Stripes burger with a gluten-free bun. The beef patty was excellent and the fries were the best I’ve had in years. Excellent service and fun atmosphere.
